The purpose of this study is to develop an A-STEAM program using the Camera Obscura. The starting point of this study is the problems which students can encounter in real-life and it is designed to enable students to establish a research project. to integrate science, technology, engineering, and mathematics with main focus being art, and to explore all the avenues of expression using the Camera Obscura. In doing so, this study proposes possibilities of enhancement of students abilities to solve the problems and the development of artistic sensibilities. The process of developing the A-STEAM Program for art as a subject follows the PDIE process model by Jinsoo Kim. This study leaves the practice and evaluation as follow-up research and develops the teaching-learning process agenda, the paper for students' activities. and the materials for teachers' guidance by reflecting on the aspects of circumstantiation, creative design, and emotional touch. 본 논문의 목적은 카메라 옵스큐라를 이용한 미술중심 융합인재교육을 위한 수업자료의 개발에 있다. 이를 위하여 본 연구는 초둥학교 5, 6학년의 미술교과서 '관찰 표현' 단원을 재구성하고 학생자신이 실제 상황에서 부딪힐 수 있는 문제를 출발점으로 삼아 학생 스스로 과제를 설정하도록 하였다. 또한 카메라 옵스큐라를 이용한 표현 및 탐구 활동을 통해 미술 중심의 과학, 기술, 공학, 수학의 연계를 시도하였으며 시행착오를 거치는 가운데 탐구 활동을 통하여 학습자의 창의적 문제해결력과 예술적 감수성 발달의 가능성을 제시하였다. 수업자료 개발 과정은 김진수 (2012)의 초ㆍ중둥학교 STEAM 교육 수업자료 개발을 위한 PDIE 절차 모형을 따라 미술 교과용 A-STEAM 수업자료를 개발하였으며, 실행과 평가 단계는 후속 연구로 계획하고 각 차시별로 STEAM 학습 준거인 상황 제시, 창의적 설계, 감성적 체험의 요소를 반영하여 교수ㆍ학습 과정안과 학생 활동지, 교사용 자료를 개발하였다.

Cellulose is an abundant biodegradable material in nature with excellent properties, but due to its poor processability, it has been widely studied for processing through modification. Cellulose acetate propionate (CAP) is a cellulose derivative in which the hydroxyl group of cellulose is replaced by acetyl and propionyl groups. CAP has several advantages, such as excellent solubility, structural stability, light and weather resistance, and good transparency. Porous nanofibers with excellent specific surface area, which can be applied in various fields, can be easily formed by the phase separation method using highly volatile solvents. High speed centrifugal spinning is a nano/micro fiber preparation method with advantages such as fast spinning and easy alignment control. In this study, a CAP/polybutylene succinate (PBS) spinning solution with chloroform as solvent was prepared to prepare porous microfibers and the fiber morphology was examined as a function of the disk rotation speed in an high speed centrifugal spinning device.
Complex Nanoparticle of Light-Emitting MEH-PPV with Au: Enhanced Luminescence
Kim, Mi Suk,Park, Dong Hyuk,Cho, Eun Hei,Kim, Kyoung Ho,Park, Q-Han,Song, Hugeun,Kim, Dae-Chul,Kim, Jeongyong,Joo, Jinsoo American Chemical Society 2009 ACS NANO Vol.3 No.6
<P>Complex nanoparticles (NPs) of poly(2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene vinylene) (MEH-PPV) NP adsorbed with Au NPs (MEH-PPV/Au NPs) were fabricated through a reprecipitation method. The formation of MEH-PPV/Au NP complexes was confirmed through high-resolution transmission electron microscopy and Fourier transform infrared experiments. The laser confocal microscope photoluminescence (PL) efficiency of the complex MEH-PPV/Au single NP dramatically increased compared with that of the MEH-PPV single NP without Au NPs, which was directly confirmed through color charge-coupled device images. The enhanced PL efficiency of the MEH-PPV/Au NP complex might have originated from the energy transfer effect in a surface plasmon resonance coupling between a MEH-PPV NP and Au NPs. The strong local field enhancement due to nanogaps between Au NPs in the background of a light-emitting MEH-PPV NP might be another origin of the PL enhancement of the NP complex, as supported by finite difference time domain calculations. We also observed the blue shift of the PL peaks of the single MEH-PPV and MEH-PPV/Au NP, compared with the solution PL peaks of those NPs.</P>

<P><B>Abstract</B></P><P>LiFePO<SUB>4</SUB> nanoparticles were grown on nano-graphite platelet (NGP) using a simple chemical route. The material was used as the cathode in Li-ion rechargeable batteries and exhibited excellent cyclability and rate capability because of the easy electron transport in it. The electrochemical stability of the electrode was improved by the two-dimensional conductive network of the NGP. The resulting electrodes delivered a specific capacity of about 150mAhg<SUP>−1</SUP> at a current rate of 135mAg<SUP>−1</SUP> (∼0.8C) after 100 cycles with no capacity fade. At elevated current rates, the electrodes exhibited capacities of more than 100mAhg<SUP>−1</SUP> at a current density of 2000mAg<SUP>−1</SUP> (∼12C) without further incorporation of conductivity agents or coatings.</P>
Novel Motion Modes for 2-D Locomotion of a Microrobot
Jinsoo Kim,Min Jun Kim,Jeonghoon Yoo,Seung-Jong Kim IEEE 2014 IEEE transactions on magnetics Vol.50 No.11
<P>This paper proposes novel motion modes for a microrobot which enable several driving options during its 2-D locomotion. The robot motion based on conventional methods shows stick-slip phenomena which produce imprecise jerking movement. We solved the imprecise control problem by using the concept of kinetic friction force. Furthermore, we introduced several motion modes that can generate smooth motion under different environments and presented the pros and cons of each motion mode. A motion mode is properly selected depending on the environment or application purpose, and it can exhibit high performance in the execution of the task. The proposed method using a suitable mode of operation of the microrobot has the potential to be applied in various medical fields.</P>

<P>Amorphous nitrogenated indium-gallium-zinc oxide (a-IGZO:N) thin films were deposited on highly doped silicon (n+Si) wafer substrates and heat-treated by millisecond flash lamp annealing (FLA) at different preheating temperatures to enhance the electrical characteristics of oxynitride thin film transistors (TFTs). A one-dimensional conduction/radiation heat transfer simulation was conducted to predict the temperature fields in the Si substrate, which indicated that the film temperatures during FLA instantaneously rose above 700°C. The electrical characteristics of the a-IGZO:N TFTs were compared with those produced by conventional furnace annealing of one hour. As a result of the FLA process, a remarkable improvement in the TFT device performance was observed in terms of the electrical output characteristics and transfer curves of the a-IGZO:N TFTs. Morphological analyses were conducted using X-ray diffraction, atomic force microscopy, and field emission scanning electron microscopy, indicating the possibility of partial crystallization of the a-IGZO:N channel layers under high-temperature annealing conditions, but the best TFT performance was found for the amorphous phase of IGZO:N.</P>

<P>We aimed to identify prognostic factors associated with progression-free survival (PFS) and overall survival (OS) in metastatic renal cell carcinoma (mRCC) patients treated with sorafenib. We investigated 177 patients, including 116 who received sorafenib as first-line therapy, using the Cox regression model. During a median follow-up period of 19.2 months, the PFS and OS were 6.4 and 32.6 months among all patients and 7.4 months and undetermined for first-line sorafenib-treated patients, respectively. Clinical T3-4 stage (hazard ratio [HR] 2.56) and a primary tumor size >7 cm (HR 0.34) were significant prognostic factors for PFS among all patients, as were tumor size >7 cm (HR 0.12), collecting system invasion (HR 5.67), and tumor necrosis (HR 4.11) for OS (<I>p</I> < 0.05). In first-line sorafenib-treated patients, ≥4 metastatic lesions (HR 28.57), clinical T3-4 stage (HR 4.34), collecting system invasion (univariate analysis HR 2.11; multivariate analysis HR 0.07), lymphovascular invasion (HR 13.35), and tumor necrosis (HR 6.69) were significant prognosticators of PFS, as were bone metastasis (HR 5.49) and clinical T3-4 stages (HR 4.1) for OS (<I>p</I> < 0.05). Our study thus identified a number of primary tumor-related characteristics as important prognostic factors in sorafenib-treated mRCC patients.</P>

<P>IRSp53 is an adaptor protein that acts downstream of Rac and Cdc42 small GTPases and is implicated in the regulation of membrane deformation and actin filament assembly. In neurons, IRSp53 is an abundant postsynaptic protein and regulates actin-rich dendritic spines; however, its in vivo functions have not been explored. We characterized transgenic mice deficient of IRSp53 expression. Unexpectedly, IRSp53(-/-) neurons do not show significant changes in the density and ultrastructural morphologies of dendritic spines. Instead, IRSp53(-/-) neurons exhibit reduced AMPA/NMDA ratio of excitatory synaptic transmission and a selective increase in NMDA but not AMPA receptor-mediated transmission. IRSp53(-/-) hippocampal slices show a markedly enhanced long-term potentiation (LTP) with no changes in long-term depression. LTP-inducing theta burst stimulation enhances NMDA receptor-mediated transmission. Spatial learning and novel object recognition are impaired in IRSp53(-/-) mice. These results suggest that IRSp53 is involved in the regulation of NMDA receptor-mediated excitatory synaptic transmission, LTP, and learning and memory behaviors.</P>
